Black-staining Polypore


The Black-staining Polypore (Meripilus sumstinei) combines the color of Hen of the Woods with the form of Chicken of the Woods (specifically Laetiporus cincinnatus). The staining on this specimen was very gradual. I cut off a piece and left it in the sun all day. (See the last picture.) This is an edible mushroom; the texture resembles Chicken of the Woods. Another similar mushroom is Berkeley's Polypore, Bondarzewia berkeleyi, which has larger pores and larger, less divided individual lobes. This mushroom was growing parasitically on the root of a Bur Oak (Quercus macrocarpa).
